What is the difference between transcutaneous pacing and transvenous pacing?
It can be used to treat symptomatic bradycardias that do not respond to transcutaneous pacing or to drug therapy. Transvenous pacing is achieved by threading a pacing electrode through a vein into the right atrium, right ventricle, or both….

What is a transvenous pacing wire used for?
Transvenous cardiac pacing can be used as a bridge to permanent pacing when permanent pacing is not available, when the pacing need is only temporary, or when further evaluation is required. Therefore, all indications for permanent cardiac pacing are indications for transvenous pacing as well.
When would a transvenous pacemaker be indicated?
Transvenous temporary cardiac pacing (TV-TP) is a potentially life-saving therapy in patients with haemodynamically compromising arrhythmias [1]. TV-TP therapy is primarily indicated for the treatment of symptomatic bradycardia and various types of (reversible) symptomatic heart block [2].
What is the difference between transcutaneous pacing and cardioversion?
The Difference between Pacing and Cardioversion Pacing corrects a slow heart rate by delivering controlled pulses to mimic a desired rhythm. Cardioversion is used to restore a fast and unstable heart rate to its normal beating rate through timed shock delivery.
Where does a transvenous pacer go?
The internal jugular vein and the subclavian vein are the most common sites of venous access for temporary transvenous pacing.
Where does a transvenous pacer sit?
The preferred route of access for temporary transvenous pacing is a percutaneous approach of the subclavian vein, the cephalic vein or, rarely, the axillary vein, the internal jugular vein or the femoral vein.
How do you do a transvenous pace?
INSERTION
- Push the tip of the pacer wire through the diaphragm into the cordis. Advance with impunity to 15cm.
- Time to turn the pacer generator on (fig 2). Your initial settings are used to find the right catheter tip position.
- Now slowly advance the pacer catheter (balloon still up).
- You can now start to tidy up.
What is temporary transvenous pacing?
Temporary transvenous pacing consists in inserting a temporary pacing electrode catheter (EC) into the right ventricle and then applying an electric stimulus with the goal of restoring effective cardiac depolarization and heart contraction, resulting in the delivery of an adequate heart rate and cardiac output [3].
How does a transvenous pacer work?
What is the difference between synchronized and unsynchronized cardioversion?
Defibrillation or unsynchronized cardioversion is indicated in any patient with pulseless VT/VF or unstable polymorphic VT, where synchronized cardioversion is not possible. Synchronized cardioversion is utilized for the treatment of persistent unstable tachyarrhythmia in patients without loss of pulse.
How do you place a transvenous pacer?

When should you not use synchronized cardioversion?
For cases where electrical shock is needed, if the patient is unstable, and you can see a QRS-t complex use (LOW ENERGY) synchronized cardioversion. If the patient is pulseless, or if the patient is unstable and the defibrillator will not synchronize, use (HIGH ENERGY) unsynchronized cardioversion (defibrillation).
What rhythms do you synchronize Cardiovert?
What Rhythms Require Synchronized Cardioversion?
- Unstable Atrial fibrillation (AF)
- Atrial flutter (types I and II)
- Atrial tachycardia.
- Ventricular tachycardia with a pulse.
- Supraventricular tachycardia.
When are transvenous and epicardial pacing initiated?
Transvenous and epicardial pacing are initiated as temporary measures when a failure of the normal conduction system of the heart to produce an electrical impulse results in hemodynamic compromise. PREREQUISITE NURSING KNOWLEDGE
Transcutaneaous pacingvia multifunction pads attached to our Philips Defib machines set on Pacer Mode. Transvenous pacingvia a pacing wire that is inserted thru an introducer in a central large vein into the right ventricle, then attached to a pacer box (pulse generator box) via a pacing cable.
What is Temporary epicardial pacing?
Temporary Epicardial Pacing. Epicardial pacing is done thru small wires placed in the myocardium during cardiac surgery. The wires are placed in either the right atria or the right ventricle (or both) and kept in place in the heart by a coiled portion in the wire.
How to install a transvenous wire pacing system?
Insertion of Transvenous Wire MD will insert the appropriate sized introducer. Under sterile conditions provide the MD with the pacing lead. They then need to apply the sterile sleeve over the lead (the sterile sleeve was in the introducer kit). MD will hand you the connector end of the pacer lead for you to connect to the pacer box.
